Concrete


Book Description

The first title in a new series aimed at sharing best practices in the conservation of modern heritage. This timely volume brings together fourteen case studies that address the challenges of conserving the twentieth century’s most ubiquitous building material—concrete. Following a meeting of international heritage conservation professionals in 2013, the need for recent, thorough, and well-vetted case studies on conserving twentieth-century heritage became clear. Concrete: Case Studies in Conservation Practice answers that need and kicks off a new series, Conserving Modern Heritage, aimed at sharing best practices. The projects selected represent a range of building typologies, building uses, and project sizes, from the high-rise housing blocks of Le Corbusier’s Unité d’Habitation and public buildings such as the London’s National Theatre to small monuments such as the structures at Dudley Zoological Gardens and a sculpture by Donald Judd. The projects also represent a range of environmental and economic contexts. Some projects benefit from high levels of heritage protection and access to funding, while others have had to negotiate conservation with stringent cost limitations. All follow a rigorous conservation approach, beginning with a process of investigation and diagnosis to identify causes and target repairs and balancing these with conservation requirements to preserve significance. Written by architects, engineers, conservators, scholars, and other professionals in the field, these highly detailed and well-illustrated studies demonstrate sound practice, rigorous methodology, and technological innovation and represent the vibrancy of the field as it stands today. This book has something to offer anyone interested in the conservation of modern heritage.




Post-Tensioned Concrete: Principles and Practice, Third Edition


Book Description

The book combines history with academic notes for use at the university level, presenting design examples from actual jobs with applications and detailing for the practicing engineer. Chapter 1 tells the history of post-tensioned concrete as only Ken Bondy can tell it. Chapters 2-8 are the notes Dirk Bondy uses to teach Design of Prestressed Concrete Structures at UCLA and Cal Poly-San Luis Obispo. Chapters 9-13 are design examples that address many of the decisions faced by practicing engineers on typical projects. Chapters 13-14 cover the art of detailing and observing the construction of post-tensioned concrete. This knowledge was obtained over many years of working on our own projects and listening and learning from the the pioneers of post-tensioned concrete. Chapter 15 covers the slab on grade industry, which represents more sales of post-tensioning tendons than all other post-tensioning applications combined. Chapter 16 discusses the challenging application of post-tensioning-external post-tensioning.

Concrete


Book Description

Beton - gestalten und konstruieren mit dem Baustoff der Zukunft Beton ist dank seiner nahezu beliebigen Formbarkeit, seiner konstruktiven Vielseitigkeit und einfachen Bautechnik der Baustoff der Gegenwart. Neben einer sorgfältigen gestalterischen und konstruktiven Planung sind Ausschreibung und Bauvertrag die Basis einer gelungenen Baudurchführung. Das Buch vermittelt das Grundverständnis zum Umgang mit dem Material mit besonderem Blick auf die Rolle des Architekten bei Planung und Bauleitung. Aktuelle Tendenzen in der Baustofftechnologie, die Entwicklung innovativer Betone werden dabei ebenso vorgestellt wie Erfahrungsberichte ausführender Architekten. Der Band erläutert darüber hinaus die Neufassung DBV/BDZ - Merkblatt "Sichtbeton".

Insulating Concrete Forms Construction


Book Description

Ever year, thousands of general contractors and subcontractors must grapple with whether to bid Insulating Concrete Form (ICF) projects, how much to charge for them, and how to manage the job. ICFs are stronger, energy-efficient, and offer great design flexibility, and their use is growing by 30% a year. This invaluable work walks the contractor through both business and technical considerations in evaluating and adopting Insulating Concrete Forms for both the residential and commercial markets. * Details the entire ICF construction process * Training and supplier information * Actual job site experiences




Concrete Dreams


Book Description

In Concrete Dreams Nicholas D’Avella examines the changing social and economic lives of buildings in the context of a construction boom following Argentina's political and economic crisis of 2001. D’Avella tells the stories of small-scale investors who turned to real estate as an alternative to a financial system they no longer trusted, of architects who struggled to maintain artistic values and political commitments in the face of the ongoing commodification of their work, and of residents-turned-activists who worked to protect their neighborhoods and city from being overtaken by new development. Such forms of everyday engagement with buildings, he argues, produce divergent forms of value that persist in tension with hegemonic forms of value. In the dreams attached to built environments and the material forms in which those dreams are articulated—from charts and graphs to architectural drawings, urban planning codes, and tango lyrics—D’Avella finds a blueprint for building livable futures in which people can survive alongside and even push back against the hegemony of capitalism.




Concrete Recycling


Book Description

The concrete industry consumes thirty billion tons of aggregate annually, almost all from non-renewable natural sources. Demolition produces a growing amount of materials which are legally usable and readily available. If not used locally they must be transported and landfilled. Also, demolition generally takes place close to new construction sites: recycling promotes shorter transportation distances, a must for improving the overall environmental footprint of the construction world. This book encompasses all aspects of this current trend: How recycled aggregates are obtained and their properties. Improving their quality through phase selection or separation. Incorporating concrete from demolition into the cement production process and the properties of the product obtained. What are the properties of concrete incorporating recycled concrete aggregates at various replacement levels, throughout the lifecycle of the material, from the fresh state to the long-term, including durability and fire. How recycled concrete can be optimised for various uses. How this new structural material can be managed in reinforced concrete construction. Solid experience from a series of experimental sites, and drawing on the Recybéton project, which lasted more than 5 years and gathered about 50 partners (from both academia and industry). Specific issues in recycled concrete quality control. National practices in the most advanced countries, and the main national and European standards. Achieving a sustainable process.
